by setting the System-Key-Switch to the STANDBY or ON position
7.2 Safety Circuit Errors
Safety circuit errors are the most common errors a user will encounter when using the X-RAD Biological
Irradiator and are caused by a safety interlock switch being “open” which prevents X-Rays from being
produced.
7.2.1 Causes
1. System-Key-Switch not in ON position
2. Emergency Switch is activated
3. Cabinet Door is open
4. Cooler has low flow
5. Tube/Cooler are operating too high of a temperature
6. Baffle is opened/off
7.2.2 Fix
1. Set the System-Key-Switch to the on position. If error not fixed continue to next item
2. Deactivate Emergency Switch by twisting switch counterclockwise. Switch will automatically
retract to its inactivated state. If error not fixed continue to next item
3. Open the Cabinet Door and re-close it. If error not fixed continue to next item
4. Check the cooler hoses for any kinks. If a kink is found, unkink it.
If none of these steps fix the safety circuit error, please contact Precision X-Ray by referring to
section 9 Support for there is no way for the user to correct the errors without the guidance of
Precision X-Ray. Possible causes are: cooler may be too low on coolant, tube/cooler may be
operating at too high of a temperature, baffle is opened/off or a safety switch may have failed.
